BIG BLUE today announced that using a large lens to concentrate the sun’s power, it captured a record 230 watts onto a centimeter square solar cell, in a technology known as concentrator photovoltaics or CPV.
The IBM research team developed a system that achieved breakthrough results by coupling a commercial solar cell to an advanced IBM liquid metal thermal cooling system using methods developed for the microprocessor industry.
That energy is then converted into 70 watts of usable electrical
power, about five times the electrical power density generated by typical cells using CPV technology in solar farms.
If it can overcome additional challenges to move this project from the lab to the fab, IBM believes it can significantly reduce the cost of a typical CPV based solar energy system
